Any jobs to practice mechanical engineering?

Ever since I was as small as I could remember, all I remember doing is breaking things apart to see how they work, then re-assembling them. I feel like I have become an expert on that. Either taking things apart and studying them or looking at instructions. I am looking forward to seeing engineering jobs available for 14-year-olds on this website. Paid or not, any engineering job will get any kid closer to being an engineer in their soon, but distant future.
